@spacedrone808 thank you,
@canonkong can you please share your modified ACPI.SYS so I can try it ? , I have issue ACPI compilate on my Asus TRX40 , CPU TR 3960x

i have uploaded this windows 7 iso made with image-burn from the usb stick used to get windows 7 on my pc (b450m board).
can not guarantee that it will work because i haee not tested it and it is the first time i tried to make an iso from a functional usb stick installer.
but it should be possible to boot from it after "burning" it to usb-stick or cd with rufus or similar program.

the nvme driver (if needed) must be load during the installation of windows 7 and is on the stick aswell, but only for samsung nvme; don't know if it will function for other models aswell.

after the installation i lost all usb ports, but with the drivercd i was able to install chipset driver for am4 and from there proceeded with the additional drivers for the motherboard / cpu etc. and the modded ones for pci/usb3.

Need some help here guys. I've tried using the drivers package included in this post and adding them into a Windows 7 SP1 Pro x64 iso. I've tried with a USB 2.0 and 3.0 drive but can only ever get the first stage installed. When it comes to booting it off the HDD it stops in different stages. It's always before the GUI though. Booting normally I just get an infinite loading windows animation. If I try safe mode it'll stop on different files, most commonly disk.sys. I've got a MSI MPG X570 Gaming Plus and Ryzen 5 3600. Thanks.

Enable CSM or try UEFISeven

I posted on this thread earlier in the year, but never got around to installing an OS (Windows 7) on the system yet. I have an X370 board and a X470 board but I recently got a B550 Taichi and this is very disappointing news that they have done this on a hardware/BIOS level. I am referring to #361. Early versions of the BIOS worked, but the ones with Zen 3 support now seem to block Windows 7 at the hardware level. At least for the 64 bit version, as the 32 bit version seems ok but this is a problem as modern systems need 64 bit. I am now questioning whether or not I want to keep this board.

Before attacking this Windows 7 thing, I wanted to wait for Zen 3, knowing the release was coming soon.. and now I'm wondering about everything. I don't mind putting in the time to learn or trial and erroring over weeks or months but there has to be a way to get it working (in the end) otherwise it's not worth it. I would rather invest my time into how to modify Windows 10 or use some other option.

Thanks so much to this forum and the users here for making the information flow and keeping these options open. Especially to canonkong for the work he has done on the drivers. During my adventure of the next few months I will share any methods I learn that can help. Or any info that can help others that I find with Zen 3 + B550 or Zen 3 + X570.

Does anyone know if this is all X570 or B550 boards that are having problems with Windows 7 or if it's just Asrock doing this? Is it the AGESA code itself, or the board makers doing their own changes to the BIOS itself? Is it best to use B450 or X470 or are there still people out there getting X570 or B550 getting this to work? It's getting harder and harder to find information about this stuff. But I will keep searching and reading around.

I've only just learned about UefiSeven today, so I have a lot of reading to do. But do you know if this method works for AM4 Ryzen systems? I've done a little reading so far and it seems like it was based around UEFI Class 3 systems like Intel Laptops that no longer have legacy support. It seems to work well for this application. But I saw some complaints that for Ryzen systems it doesn't work. Does anyone have any links they could share for success stories when using UefiSeven?

OK, so an external PCI card with USB 2.0 ports would work?

I think it's just asrock, because canonkong has b450 from asus and seems even latest asus x570 dark hero working with windows 7, as i saw a CPUz Screenshot and video by extreme OC Elmor
https://valid.x86.fr/ffuppx

I already wrote a mail to asrock support, but bacause now i have an 5000 series cpu (ryzen 3000 sold) and x570, they wont do anything, bacause it was not tested and is not officially supported.
They also wrote because of canonkongs Screenshot that b450 is still sopported by amd for Windows 7.
Thats why i wonder if asrock b450 boards with ryzen 3000 and later bioses are working too or not. Because for b450 amd has still windows 7 Chipset drivers.

Bacause there are only a few user with windows 7 and ryzen 3000, its hard to verify wich boards or BIOS versions are working.

Maybe if more users would write to asrock support they would look at it.
I just wrote to german support.


Its really disappointing if asrock would be the only board manufacturer that does not work with windows 7, even if i still did not see msi or gigabyte users with windows 7

Wish me luck, i'm going to install a 3950X with my current install of Win7 Enterprise on a CH7.
